这可能仅从HTML文件中提取所有文本吗？

我正在考虑删除所有格式，所有文本就像您转到网站的任何页面，用户Ctrl + A和Ctrl + C，然后使用Ctrl + V将所有内容粘贴到记事本中。你会明白我的意思是只提取所有的文本....让我们用一个网站，一个更好的解释：这个网站： https://developer.palm.com/content/resources/develop/quick_start_ios.html 这可能仅从HTML文件中提取所有文本吗？

而且我想要的东西：

If you've been developing for iOS® and are looking to expand your audience, we're here to help. Getting started with webOS is easy! If your current focus is OpenGL/SDL, then the transition will be simplicity itself. We have lots of great stories of developers porting their OpenGL apps very quickly. You can use the publicly available 3.0 SDK to do OpenGL/SDL development now with the included Plug-in Development Kit (PDK). Best of all, the PDK integrates nicely with Xcode. 

If your focus is web app development, you'll want to look at Enyo, our next-generation JavaScript framework, which is included in the 3.0 SDK. 

Ready to get started? 

Download the SDK 
It's free! (While you're at it, sign up for the Developer Program.) 

Try the Enyo tutorial or the OpenGL sample app 
Choose the sample that's most appropriate for your skill set. 

Check out our Resources pages 
Get more information on developing for webOS. Or go straight to the Reference section to get all the details.

我用lynx，从终端试试这个：

lynx -dump http://www.google.com

只有在您安装了lynx的情况下，才能在linux下运行。 – Shoan

这应该工作

<?php 

echo strip_tags(file_get_contents("https://developer.palm.com/content/resources/develop/quick_start_ios.html"));

那的总体思路。你可以做像str_replace('<br/>', '\n', $output)这样的东西来更好地进行格式化。

什么是downvote？这个问题已经被标记为php，并且上面的代码有效......任何人都低估了请解释。 – arunkumar

另一种方式来做到这一点是检索页面的身体标记值：

$html = new DOMDocument(); 

$html->loadHTMLFile("https://developer.palm.com/content/resources/develop/quick_start_ios.html"); 

$body = $html->getElementsByTagName("body"); 
$body = $body->item(0); 

echo $body->nodeValue;

您可以使用文档树要做到这一点，只是把所有的文本节点，并删除所有的元素节点。

你可以使用javascript或C++与webkit实现这一点。
